The above link is to an article about the impact the NEO Apophis would have if it impacts Earth:This quote...

"The explosion would have blotted out sunlight, caused rocketing global warming and killed off all plant life."

...completely goes against everything that has been considered conventional wisdom. Ever hear of "nuclear winter"?

Now, a site called "enterprisemission.com" explored global warming a few years ago, and the question of why every instrument NASA has in the solar system is showing higher than expected temperatures, thought to be a major reason why Spirit and Odyssey are still functional after all of this time.

Now, stepping away from the various agendas, here are the facts:There are over 8 billion humans, all exhaling carbon dioxide.The planet's scrubbers, its forests, are being cut down at an alarming rate. See if you can create a link between the deforestation of the Amazon and the increase in the atmosphere's CO2 level. WWI and WWII caused more pollutants to be dumped into the atmosphere than at any time in Earth's history.

The simple facts are that the agenda is being driven by nebby people who believe that everyone should live like they want them to live. It has gotten to the point where the local paper is bombarded by letters of protest for even joking about global warming.

But simplified, we are on our own "Apollo 13", and there are too many of us and not enough trees. We need more trees!

Anyway there are signs in the solar system that recommend further studies of the sun.

I read too of "global warming" on several planets (source I believe space.com) on separate articles. So far Mars has been hotter than expected, then Urane (or Neptune?) then Pluto. Extreme weather on Jupiter, a new red spot appears. Extreme weather on Mars, a dust storm covers almost all the surface of the planet.

Now this activity on the Sun south pole... sounds almost as good news.
